Description

Technical Field

[0001] The utility model relates to the field of sampling devices, in particular to a river bottom mud sampling device for hydrology and water resources. Background Art

[0002] With the continuous development of social economy and the continuous improvement of people's living standards, people pay more and more attention to health. Water is the source of life and people's lives cannot be separated from water. The drinking water in people's lives is obtained through a series of impurity filtration operations. Generally, before using river water resources, it is necessary to test and study the water and riverbed mud of the river. Among them, the detection of riverbed mud requires the use of river bottom mud sampling device.

[0003] Chinese patent number CN202221101765.0 discloses a river sediment sampling device for hydrological and water resources engineering, including a bottom plate, a fixing frame is fixedly connected to the top of the bottom plate, a first fixing hole is opened on the top of the fixing frame, a motor is arranged above the bottom plate, a fixing block is fixedly connected to both sides of the inner wall of the fixing frame, a second fixing hole is opened on one side of the two fixing blocks, a screw rod is arranged above the bottom plate, both sides of the screw rod are rotatably connected to the inside of the second fixing hole respectively, a slide groove is opened on both sides of the inner wall of the fixing frame, a moving block is arranged above the bottom plate, the inside of the moving block is threadedly connected to the outer surface of the screw rod, a fixing rod is fixedly connected to one side of the moving block, and an electric push rod is fixedly connected to one side of the fixing rod.

[0004] From the above, it can be seen that the motor, screw and moving block are set, and the output shaft of the motor rotates to drive the screw to rotate, and the screw rotates to drive the moving block connected to the outer surface of the screw to rotate up and down. Through the set slide groove and the slider set on the moving block, the slider slides inside the slide groove, and then limits the moving block, so that the moving block can only move up and down along the screw, thereby driving the fixed rod, the electric push rod and the connecting block to move up and down, which solves the problem that the sampling device can only collect samples from areas close to the edge of the river when in use, resulting in the taken sediment samples not being representative for detection. However, the case also has the following shortcomings: when sampling river sediment, the current existing technology can only sample at a preset angle and fixed point. When the whole is not moved, it cannot be adaptively adjusted according to the different positions of the sampling points.

[0005] Therefore, in view of the above problems, a river sediment sampling device for hydrology and water resources is proposed. Utility Model Content

[0024] See also Figure 1-Figure 5 As shown, a river sediment sampling device for hydrology and water resources comprises a base 1, a movable sampling device 2, and a position changing component 3; the movable sampling device 2 is installed with a connecting seat 21, a connecting shaft 22 is fixedly installed on the top of the connecting seat 21, a first-stage movable arm 23 is penetrated and movably installed on one side of the connecting shaft 22, a connecting plate 26 is fixedly connected to the bottom of the first-stage movable arm 23, a first plunger 25 is hinged at the bottom end of the connecting plate 26, one side of the first plunger 25 is movably installed on the output end of the first hydraulic cylinder 24, and the other side of the first hydraulic cylinder 24 is hinged to the connecting seat 21;

[0025] During operation, the first-order movable arm 23 is supported by the connecting shaft 22 installed on the top of the connecting seat 21. During the support, one side of the first-order movable arm 23 is limited by the cooperation of the first hydraulic cylinder 24 and the first plunger 25. When sampling is required, one end of the first plunger 25 is linked with the connecting plate 26 to drive the first-order movable arm 23 to flip around the connecting shaft 22 to control the grabbing height.

[0026] Further, the position changing component 3 is installed with a box body 31, a servo motor 32 is fixedly installed on one side of the box body 31, a worm 33 is fixedly installed on the output end of the servo motor 32, one side of the worm 33 is drivingly connected with a worm wheel 35, one side of the worm wheel 35 is penetrated and fixedly installed with a movable disk 37, and the bottom of the movable disk 37 is fixedly connected with a connecting seat 21;

[0027] During operation, when the worm 33 rotates, it transmits the power to the worm wheel 35 , and the worm wheel 35 drives the movable disk 37 and the connecting seat 21 on the top of the movable disk 37 to rotate synchronously, and the sampling position is adjusted with the rotation.

[0028] Furthermore, the bottom of the box body 31 is fixedly mounted with the box body 31, one side of the box body 31 is fixedly mounted with a first fixed bearing 34, one side of the first fixed bearing 34 is penetrated and movably mounted with a worm 33, the bottom of the box body 31 is fixedly mounted with a second fixed bearing 36, and the top of the second fixed bearing 36 is movably mounted with a movable disk 37;

[0029] During operation, when the servo motor 32 and the movable disk 37 rotate, the first fixed bearing 34 and the second fixed bearing 36 perform corresponding support and limitation to prevent the transmission connection between the worm 33 and the worm wheel 35 from being interrupted, causing the movable disk 37 and the connecting seat 21 to be unable to move.

[0030] Furthermore, a second hydraulic cylinder 27 is hinged on the top of the connecting plate 26, a second plunger 28 is movably mounted on the output end of the second hydraulic cylinder 27, a second-stage movable arm 29 is hinged on the other end of the second plunger 28, and a first-stage movable arm 23 is hinged on the top of the second-stage movable arm 29;

[0031] During operation, the second hydraulic cylinder 27 drives the second plunger 28 to extend outward, and one end of the second plunger 28 generates a thrust on the second-stage movable arm 29, causing the second-stage movable arm 29 to move around the hinge of the first-stage movable arm 23, thereby increasing the distance for sampling the river sediment during the movement.

[0033] During operation, the second-order movable arm 29 is hinged with the fixed block 201 so that the fixed block 201 can be moved while being limited, so that it always remains vertically downward due to its own weight, which is beneficial to increasing the sampling efficiency of river sediment.

[0034] Furthermore, linkage arms 204 are movably mounted on the tops of the two sampling claws 205, and the tops of the two linkage arms 204 are hinged with fixed blocks 201;

[0035] During operation, when the push rod 203 moves, the sampling claws 205 on both sides are linked to move around the connection of the linkage arm 204 as the axis, and the linkage arm 204 is hinged to the cylinder 202 under the fixed block 201, which is conducive to making the bottoms of the sampling claws 205 on both sides fit together for salvage and grabbing.

[0036] Working principle: In the first embodiment, when it is necessary to sample the river sediment, the hydraulic energy of the first hydraulic cylinder 24 is converted into the mechanical energy of the first plunger 25 by driving to perform linear reciprocating motion. When the first plunger 25 moves, one end of the first plunger 25 is linked to the first-order movable arm 23 through the connecting plate 26 to perform circular motion with the connecting shaft 22 as the axis, thereby driving the sampling claw 205 to move up and down with different moving distances. At the same time, when the second hydraulic cylinder 27 is driven to move the second plunger 28, the angle between the first-order movable arm 23 and the second-order movable arm 29 will be changed, and the grasping distance of the sampling claw 205 will change accordingly. When the sampling claw 205 contacts the river sediment, the cylinder 202 is driven to shrink the push rod 203, so that the push rod 203 links the sampling claws 205 on both sides to move relatively, and the sampling claws 205 on both sides cooperate to sample the river sediment.

[0037] In the second embodiment, the servo motor 32 is driven to rotate the worm 33 at the output end, and the worm 33 transmits the worm wheel 35 during the activity to ensure that the rotational movement of the worm wheel 35 is controlled by the servo motor 32. The rotational movement of the worm wheel 35 drives the fixed movable disk 37 to rotate synchronously. At the same time, the movable disk 37 is used to support and fix the connecting seat 21 to realize the 360° position change of the movable sampling device 2 for sampling the river sediment.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
